Display and HMI Considerations for Industrial Automation Panels

In the realm of industrial automation, the design and functionality of displays and Human-Machine Interfaces (HMIs) play a critical role in ensuring efficiency, usability, and safety. This article outlines the essential considerations for selecting displays and HMIs for industrial automation panels, helping engineers and procurement managers make informed decisions.

Key Considerations

1. Environment: Understand the operating conditions of the automation panel. Factors such as temperature, humidity, and exposure to dust or chemicals may influence the choice of display technology. For instance, a sunlight-readable TFT LCD may be necessary for outdoor applications.

2. Display Type: Different display technologies serve various applications. Here are common types:

   • TFT LCD Displays: Offer high resolution and vibrant colors, suitable for complex data visualization.
   • Segmented LCDs: Cost-effective for displaying simple information like digits or icons.
   • OLED Displays: Provide high contrast and wide viewing angles, ideal for low-power applications.
   • Touch Panels: Capacitive or resistive touch interfaces allow for intuitive user interaction, but the choice depends on environmental conditions and user preferences.

3. Size and Resolution: The size of the display should match the intended use and available panel space. Common sizes include 7-inch and 10-inch modules. Higher resolution allows for more information to be displayed without overwhelming the user.

4. User Interface Design: A well-designed HMI enhances user experience. Consider the following:

   • Simplicity: Keep the interface intuitive, avoiding clutter.
   • Feedback: Ensure that the display provides responsive feedback to user inputs.
   • Accessibility: Design for users with varying levels of expertise, ensuring that critical information is easily accessible.

5. Connectivity Options: Ensure that the display supports the necessary communication protocols (e.g., UART, SPI, I2C) for seamless integration with the control systems.

6. Durability and Reliability: Industrial environments can be harsh. Look for displays with appropriate IP ratings and robust construction to withstand vibrations, impacts, and exposure to contaminants.

7. Power Consumption: In automation systems, energy efficiency is crucial. Select displays that balance performance with low power consumption, especially for battery-operated devices.

How to Choose the Right Display and HMI

When selecting displays and HMIs for industrial automation panels, consider the following checklist:

• Assess Environmental Conditions: Determine if the display will be exposed to harsh conditions, including temperature extremes or moisture.
• Evaluate Display Requirements: Identify what information needs to be displayed and how complex the graphics will be.
• Choose the Right Technology: Based on the assessment, select the appropriate display type (TFT, OLED, etc.) that meets your needs.
• Design User-Centric Interfaces: Collaborate with end-users to design interfaces that are comfortable and efficient for their tasks.
• Test for Compatibility: Ensure that the chosen display works well with existing systems and protocols.
• Evaluate Vendor Capabilities: Consider suppliers like BIBA Electronics who can provide tailored solutions, including custom display designs that meet specific industrial requirements.
